The invention presented is a transformable floating dock system comprising a stationary floating dock section with a pair of movable floating dock sections operatively attached to each end of the stationary dock. The transformable floating dock system can be moved into different configurations by rotating the movable sections around each other and around each end of the stationary dock to form different configurations of the dock system. The configurations can be transformed without entering the water or moving the stationary dock system.

A buoyant pool float for floating in water is disclosed. In one embodiment, the buoyant pool float includes a hingedly connected upper flotation member and lower flotation member. In a deployed position, the buoyant pool float provides an open unfolded engagement between the upper flotation member and the lower flotation member such that a continuous human reclining surface is provided from the upper end of the upper body to the lower end of the lower body. In a storage position, the buoyant pool float provides a closed folded-flat engagement between the upper flotation member and the lower flotation member such that the lower flotation member is nested against the upper flotation member.

A floating construction comprising a container filled fully or partially with water, the lower portion of the container being located within a surrounding body of water and the water surface level of the surrounding body of water being substantially lower than the water surface level inside the container, the container comprising transparent walls or walls with transparent sections and at least one open opening for entering the container, which at least one open opening is located below the surface level of the surrounding body of water, and which floating construction comprises space for spectators observing activities taking place inside the container, wherein the floating construction comprises at least one ballast tank, which ballast tank is connected to the container with a controllable pressure connection, and which ballast tank has controllable water connection to the surrounding body of water.

The present invention proposes a baby float with a massage function, which includes a float body and further includes a bubble massage component. The bubble massage component includes an air pump and an air pipe; an air outlet end of the air pump is communicated with the air pipe; and the air pipe is arranged below the float body. In the baby float, the air pipe with air holes is arranged below the float body so that the air holes can be underwater when used, and the air pump can be activated to blow out bubbles from the air holes of the air pipe. The bubbles break when coming into contact with the body of a baby, to play a role of massage.

The human powered hydrofoil bicycle includes multiple subsystems integrated together including a structural frame subsystem with associated steering and tiller module, a hydrofoil subsystem to provide vehicle lift, and a powertrain subsystem. The structural frame subsystem may be fitted with buoyancy modules to provide the overall vehicle with a near neutrally buoyant character. The structural frame subsystem also supports a seat for an operator and provides structural support for the steering and tiller module for the hydrofoil subsystem and the drivetrain subsystem. The hydrofoil subsystem includes multiple hydrofoil elements at lowermost portions of the vehicle. These hydrofoil elements generally include in a preferred embodiment a larger rear foil and a smaller front foil. The powertrain subsystem generally includes pedals rotatably supported on the vehicle at a convenient location for engagement and driving by feet of an operator. Power transmission elements extend from the pedals down to a prime mover such as a propeller.

A flotation device includes a main body portion having a leg rest, seat, back rest, and headrest. Arms are adjustably attached to the back rest via hinge mechanisms which allow the arms to be pivoted towards and away from the main body portion, and which allow the length of the arms' extension from the main body portion to be adjusted. In alternative embodiments, cupholders are secured in apertures in the arms, with headrest extensions providing additional buoyance to the head rest portion.
